Syntax

public readonly struct FramesContext_ref : IEquatable<FramesContext_ref>, IReference<FramesContext>, IAVPointer<_AVHWFramesContext>

Properties

DeviceContext

The internal parent device context managed by the enclosing frames context

Declaration

public DeviceContext_ref DeviceContext { get; }

Property Value

Type	Description
DeviceContext_ref

Height

The allocated dimensions of the frames in this pool.

Declaration

public int Height { get; }

Property Value

Type	Description
int

HwFormat

The pixel format identifying the underlying HW surface type.

Declaration

public PixelFormat HwFormat { get; }

Property Value

Type	Description
PixelFormat

IsEmpty

True if the instance does not contain any Frames Context.

Declaration

public bool IsEmpty { get; }

Property Value

Type	Description
bool

IsReadOnly

Indicates whether the device context is read-only. If true, attempting to modify the context will result in a NotSupportedException.

Declaration

public bool IsReadOnly { get; }

Property Value

Type	Description
bool

SwFormat

The pixel format identifying the actual data layout of the hardware frames.

Declaration

public PixelFormat SwFormat { get; }

Property Value

Type	Description
PixelFormat

Width

The allocated dimensions of the frames in this pool.

Declaration

public int Width { get; }

Property Value

Type	Description
int

Methods

AsVulkan()

Returns the internal hwctx as a VulkanFramesContext.

Declaration

public VulkanFramesContext AsVulkan()

Returns

Type	Description
VulkanFramesContext

Equals(FramesContext_ref)

Determines whether the current FramesContext_ref is equal to another instance of FramesContext_ref.

Declaration

public bool Equals(FramesContext_ref other)

Parameters

Type	Name	Description
FramesContext_ref	other	The other FramesContext_ref to compare with.

Returns

Type	Description
bool	true if the instances are equal; otherwise, false.

Equals(object?)

Determines whether the current object is equal to another object of the same type.

Declaration

public override bool Equals(object? obj)

Parameters

Type	Name	Description
object	obj	The object to compare with the current object.

Returns

Type	Description
bool	true if the objects are equal; otherwise, false.

Overrides

ValueType.Equals(object)

GetHashCode()

Returns a hash code for this instance.

Declaration

public override int GetHashCode()

Returns

Type	Description
int	A hash code for the current object.

Overrides

ValueType.GetHashCode()

GetReferencedObject()

Gets the object currently being referenced. Or a copy if the type is nor reference counted.

Declaration

public FramesContext? GetReferencedObject()

Returns

Type	Description
FramesContext	The referenced object of type FramesContext if available, or null if not.

SetReferencedObject(FramesContext?)

Sets the reference to a new object of type FramesContext or creates a copy if the type is not reference counted or unlinks the current reference.

Declaration

public void SetReferencedObject(FramesContext? device)

Parameters

Type	Name	Description
FramesContext	device

FramesContext_ref	left	The first instance to compare.
FramesContext_ref	right	The second instance to compare.

Returns

Type	Description
bool	true if the instances are equal; otherwise, false.

operator ==(FramesContext_ref?, FramesContext_ref?)
